IMPROVEIEN'T IN CERN-POWER.

'I'ho Sohodnle r'efen'ed to in the Lotto" Patent and making part of thename.

To whmn it may camera:

Be itknown that I, DAVID McOUBnY, of Ottawa,

in the county of Pntnam, and State of Ohio, have in-.

vented 'a' new and useful Improvement in Ohm-n Power; and I do declarethat the following is a true and accurate description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, and being apart of this specification.

The nature of this invention'relates to an improved method of connectingthe reciprooating da'sh-rod of a churn with the rotary power from whichit receives motion. i

In the drawings- A, A', and B represent thelegs of a tripod, in which achurn is secured by a lever, clamp, or other appropriate device.

The legs A A' are connected at the top by a crosstie, '0, over thecentre of the churn', while' the leg B, extending a little above the topof the churn, has se- 'cured to it a mctallic standard, D., ona'horizontal arm projeeting therefrorn.

An internally-geared wheel, E, is rotated by a handorank, e, which wheelalso rotates a pinion,`G, secured to a. shaft, rotating inproperbearings in the standard.

On the opposite end of this shaft issecu'l'ed a. balanoe-wheel, H, oneof whose arms is slotted,v as at I. In this slot issecnred an adjustablewrist-pin, J, pivoted in 'the lower end of the eonnecting-rod K.

lPivoted in the upper end of the conncoting-rod is a clip, L, in whichthe dash-rod M enters, and is secured by a thumbv-screw, l, in the clip,forcing it against one side of the same.

v The 'cross-tie O is recessed directly over the centre of the ohm-n, toform a guide for the dash-rod in its reciprocat-ing movement.`

c isl a notehed latch pivoted to the cross-tie, embracing the dash-rod,and held in place by a button, c'.

vThe length of the stroke of the dash-rod is adiusted by moving thewrist-pin J in the slot I.

The depth to which the. dasher descends into the chnrn is' regnlated byattaching and securing th'e clio at the proper point ou the dash-rod.

It will be readily seen that 'all the partsare' easily detached, topermit the removal of the chum from the tripod, by throwing out thelatch from the-cl'oss-tie, and a few turns'of the thnmb-screw I, to'permit the dash-rod to be withdrawn from the semlcirclai' recess in theclip.

What I'claim as my invention, and desire to secure by Letters Patent,is-- In chnrn-powers, the combination of the semicircular recessed clipL, provided with a thumb-screw, l,- with the connecting-rod K, wrist J,slotted balance-wheel -H, pinion G, nternally-geared wheel E, crank o'zstandaid D, tripod A, A', and B, cross-tie O, notched latch c, buttonc', and'dash-rod M, when constructed,arranged, and operating as hereindescribed, and for the purpose specified. w
